If it's a student population that is attributed to the bulk of the unverified provisionals, then it's a good bet that MoveOn.org is sweeping students into the voting places requesting provisional ballots.
The latest communication is that the precincts did not verify these provisional ballots until later, but they are indeed valid, so the point is moot.
The issue then is to King County's 123 unverified provisionals who were not properly registered, hence invalid.
The issue is also to the totality of unverified provisionals, whether later determined to be valid or not.
The question remains to screen all 'valid votes' versus all 'counted votes'.
If a provisional was cast and counted unverified but later determined to be cast by a properly registered voter, then is it disallowed based on errors by polling inspectors or allowed because the voter was not at fault? My guess is the latter. If that is the case, then the discovered unverified error in Eastern Washington is a moot issue and will have no bearing on the case because election workers have stated the votes were cast by properly registered voters. If is the former, then a precinct analysis should show the vote subtraction going against Gregoire.
I would think the democrats are in an uncomfortable position here.
Other things to ponder. Democrats are saying they have also found over 400 felons voting in Rossi favoring counties.
Also, some law professors believe the result could be neutral, not knowing who won the election, but they claim this will go against the republicans because it must be shown the outcome must appear to be different, not that it is indeterminant.
